Equivalent circuit parameters of planar transmission lines with spoof surface plasmon polaritons and its application in high density circuits.

摘要: In this paper, the characteristics of a class transmission lines which support spoof surface plasmon polaritons are investigated both numerically and experimentally. order to provide characteristic impedance for PCB designers, equivalent circuit parameters microstrip line periodically structured on subwavelength scale extracted with numerical method. It is found that significantly vary frequency when periodic structure introduced into edge conventional line. The results time-domain measurements show have remarkable advantage over can be directly used in actual high-speed circuits, helpful eliminating doubts whether metamaterials circuits.
